Sinkhole session (NH 8.6) at EGU 2012
we would like to draw your attention on the following forthcoming
Scientific Session on Sinkholes at the General Assembly of EGU in
Vienna, next April:
Session NH8.6 "Sinkholes: from susceptibility to risk evaluation and
mapping" at EGU General Assembly (Vienna, 22-27 April 2012)
Convened by: Mario Parise, Giulio Iovine, Stefania Nisio
Sinkholes are widespread in many countries of the world, in several geological and morphological settings, affecting distinct lithotypes either in the detrital cover sequences or in bedrock outcrops. In particular, some phenomena develop in geomorphological context characterized by plain areas and notable detrital coverages, either made of sediments or colluvial or residual terrains, thick even tens to hundreds of meters. In some cases, the genetic mechanisms are poorly understood; they can be quite complex and appear not directly connected with classical karstic processes. The recent urban development and the increasing need of spaces for infrastructures in areas potentially affected by sinkholes require a better comprehension in terms of related susceptibility, hazard and risk. The session aims to stimulate the discussion on the state-of-the-art of the studies on the mentioned topic, with special regard to sinkholes in plain not-karstic areas. Analyses of genetic mechanisms, methodological examples of investigation, and case studies are welcome, as well as description of techniques for evaluating susceptibility, hazard and risk.
Note: A selection of studies presented at this session will be considered for publication in a special issue of a relevant international journal.
For info on how to submit an Abstract see this page.
or go directly at the sessions page, choose Session NH8.6, and press "Abstract submission"
The deadline for the submission of Abstracts is 17 January 2012.
In case any technical questions arise, please contact us.

We hope to see you in Vienna!

Springer-Verlag has recently published the book "Dynamic Tectonics and Karst" by Prof Stefan Shanov and Assoc Prof Konstantin Kostov from the Geological Institute of Bulgarian Academy of Sciences The monograph has the following main contributions: 1 Complete historical overview on the accomplished studies of the relationship “karst & tectonics”; 2 Pointing out the significant role of the tectonic stress fields as a factor controlling the karst processes; 3 Proposition of a complex methodological approach for paleoseismological studies in karstic caves This book collects the current state of knowledge on the relationship between karst and dynamic tectonics and presents a new methodology to its study It puts forward several approaches for studying of recent geodynamics in karst terrains, such as tectonic stress fields reconstructions using structural analysis of the fracturing, geophysical studies of the rock anisotropy and fault-plane solutions from earthquakes, analysis of the spatial orientation and absolute dating of deformed speleothems, instrumental and mechanical measurements, monitoring, and modeling – all supported with case studies from several karst areas worldwide, eg in Albania, Bulgaria, Cuba and France Reference: Shanov, S, Kostov, K, 2015 Dynamic Tectonics and Karst Series: Cave and karst systems of the World Springer, Heidelberg, 123 p, ISBN 978-3-662-43992-0 Link: http://wwwspringercom/earth+sciences+and+geography/geology/book/978-3-662-43991-3. ...

Dear Colleagues: This is an invitation for you to participate in an important session on "Evaporite Karst in the Greater Permian Basin of Texas, New Mexico, Oklahoma, Kansas, and Colorado" I will chair the session at the South-Central Section, Geological Society of America (GSA) meeting that will be held in Stillwater, OK, on March 19-20, 2015 Work being done by you or your colleagues on dissolution of evaporites (gypsum, salt, potash), brines generated, brine emissions, dissolution processes or results, caves, cavities, sinkholes, collapse features, engineering/environmental problems, etc, are all appropriate for the session The work can be a state-wide or regional survey, or site specific, and the evaporite karst can be either natural or human induced Oral and/or poster presentations are welcome An earlier session on "Evaporite Karst and Engineering and Environmental Problems in the United States" was convened by James Neal and me at the 2002 Annual Meeting of GSA, and we published the proceedings of that session as Oklahoma Geological Survey Circular 109 Now I want to focus on evaporite karst in Permian strata in the extended Permian Basin of Texas, New Mexico, Oklahoma, Kansas, and Colorado It is my hope that we can pull together the upcoming-GSA presentations (plus a few others) into a well-deserved publication, after the Stillwater meeting The attached map shows the approximate extent of the Permian salts, but I know that Permian gypsum/anhydrite beds extend beyond the salts in some of the shelf areas, and these strata are also fair game This map covers a vast area of the southern Great Plains, east of the Rockies, and I know there are many projects that are (or have been) carried out in the area that have not yet seen publication, or where new work is leading to modified and/or updated reports Submit your abstract online at: wwwgeosocietyorg/sections/sc/2015mtg Then open the link “Call for Papers,” then open “Please submit your abstract online,”, then open “1 Theme Sessions,” then open “4 Evaporite Karst…,” then fill out the “Abstract Characterization” and subsequent links (and FINALLY, you are finished) The deadline for abstract submittal is December 16, 2014 Some of you reading this are not now working on Permian Basin evaporite karst, but I would appreciate it if you would pass this on to colleagues who may be able to contribute Thanks for your consideration of this request, and I look forward to hearing from (and seeing) many of you in Stillwater next March Ken Johnson, Retired Oklahoma Geological Survey. ...
